There is a save for going viral provided by my friend RageSoul51.
Unfortunately I couldn't get the trophy to pop on his save as it was glitched.Tried twice no trophy.
So ultimately I started carefully gathering these symbols so that it doesn't glitch and voila I present you the save for going Going Viral.(3 are left).Make sure that after each symbol you see a saving icon.If not the trophy is glitched and reload the save again.
Resign.Set the language to welsh from the option menu and save.Now continue and Go to the big ass cube in the middle and continue.You will be in a train station.Solve the puzzle and the train will arrive.
You will earn First Class Ticket
Next do not board the train.just outside the train you will see the symbol.press square to Collect it (1 out of 3)
Next continue with the story and solve the bell and axe puzzle.Ultimately you will auto collect the last two symbol while heading for the last part(3 out of 3)
and voila you will earn
Going Viral
Finish the game and the last section with 40 secs remaining to get The Final Countdown
